TO ALL WHOM IT MAY GONCERN:

Be it known that I, GORHAM ABBOT, of the city, county, and State of New York, haveinvented a new and improved Modeot` Making Globes; and I do hereby declare that the following is a full and exact description of the Sam`e,reference being had to the accompanying drawings, making a part `of this specification.

I-print my globes in lune-shaped sections, in the ordinary way, on any materialcombining flexibility with strength and durability. Some kinds of paper answer the purpose very Well, but parchment or a clos:elywoven fabric is better.

A very excellent material for the sections is prepared by running a very thin tissue of, rubber, in a manner well known to all manufacturers of rubber cloth,'uponcotton, linen, silk, or mixed goods. The sections then may be printed on the cloth face, or on the rubber face, or they may be printed on the clothI first, and then have a transparent sheet of rubber run over the printed face.

The printed sections are sewed together, and made up'in the globe-form, `or they maybe cemented to`som-c rm rnziterial, such as canvas, leather, or felt, made up in theglobe-form in sections, or made without seams, like hat-bodies, it' felt be used. Y

This outer covering I `distend into the globe-form, by the use of anelastic inflatable rubber bag, or with cork, sponge, hair, or any other light elastic substance. i

In sewing the sections together, I sometimes uuderlay the seams with strips orvgorcs of India-rubber tissue or cloth, in order to hold the edges more firmly together, and prevent their separating by the expansive force ofthe i-nilation or distension. v A

In making very large globes, I find it useful to place an intermediate covering between the outer globe and the inner bag, as shown ini-5g. 2.

A tube, A, atene of the poles, 'with a valve,lb, furnishes the means for inflating the'globe at pleasure, andV a rod or firm tube runningvthrough the centre, with a nut attached to each pole', supplies an axis for mounting the globe, and illustrating the revolutions ofthe earth. I

Figure 1 shows six of the sections, forming one-half ofthe globe.

Figure I is a polar section of the globe before being distended, as above described. The red lines show the v inner rubber inlatingebag.

Figure 2 is a polar section of the iniated globe. In this figure is shown au intermediate covering between the outer globe and the iniiating-bag. 4 i

Figure 3 is a perspective view ofthe completed gl0be.

What I'claim as my invention, is-

A' globe, constructed of flexible material, and distended by means of an elastic iniiatablc rubber bag,'or with cork, hair, sponge, or other light elastic substance,substantially as described.
